Title: Atmospheric pressure chemical vapor growth device
Inventor: IKEDA YASURO
IPC: C30B35/00
Filed: 1989-07-19
Abstract: PURPOSE:To efficiently expel the exhaust gas after reaction with good efficiency and to improve the film quality on a substrate surface by bringing the front ends of exhaust gas guides enclosing a gas dispersion head closer to the substrate from the front end of the gas dispersion head at the time of formation of the thin film by a chemical vapor reaction on the substrate by blowing gaseous raw materials from the gas dispersion head onto the substrate. CONSTITUTION:The substrate 108 on a susceptor 109 is heated to the reaction temp. of the gaseous raw materials by a heater 110 and while the substrate is moved horizontally by pulleys 112a, 112b, O2 and SiH4 as reaction gases are blown from plural slit-shaped nozzles 113a of the gas dispersion head 113 through respective mass flow controllers 102, 104 to the substrate 108 to form the thin film of SiO2 by the blowing vapor reaction. The ratio of the long side/short side of the slit-shaped gas dispersion head is specified to <=2.0 in this case and the spacing 107a between the surface of the substrate and the front end of the gas dispersion head 113 is set larger than the spacing 107b between the front ends of the exhaust gas guides 106 enclosing the same and the substrate 108, by which the amt. of the atm. air to be sucked from the outer side of the exhaust gas guides 106 is decreased and the exhaust gas is smoothly expelled from the substrate surface and, therefore, the deterioration in the quality of the SiO2 film on the substrate is prevented.

IPC: B21B37/66
Filed: 1981-11-20
Abstract: PURPOSE:To imrove the accuracy of sheet thickness control of a titled device, by previously storing a positional deviation signal controlled so that a rolling load is zero under the zero state of a position controlling signal, and overlapping said deviation signal on a sheet thickness controlling signal. CONSTITUTION:In a state of a kiss-roll produced by bringing an upper roll into close contact with an lower roll, that is, under the zero state of a position controlling signal 6, the upper and lower rolls are rotated to detect a rotating angle by a backup-roll rotating angle detector 3 attached to a backup roll 4. A positional deivation signal 7 of a rolling force controlling system 17 corresponding to the said rotating angle is previously stored by a storing device 12. The stored signal 7 is made to a screw position changing-extent 9 by an integration type rolling reduction system 8 at the time of rolling, and is converted into a load changing extent 11 through the mechanical characteristics 10 of a rolling reduction mechanism. Next, the changing extent 11 is converted into a screw controlling extent 14 by a mill elongation converter 13 to be overlapped on the position controlling signal 6.

Title: Paper feeder of image recording apparatus
Inventor: HAMAYA SATOSHI
IPC: B41J13/076
Filed: 1994-08-09
Abstract: PURPOSE:To prevent an abnormal vibration noise of a recording paper sheet by providing an intermediate transport part comprising an always rotated driving roller and a driven roller pressed to the driving roller, and disposing a vibration preventing weight on a shaft rotated in a body with the driven roller. CONSTITUTION:Recording paper sheets P are separated one by one by a paper feed roller 2 and a separating click 5 and supplied from a paper feed cassette 3 to an intermediate paper feed part. Further, the paper sheet is transported through a reversing guide plate 7B to a registration part by intermediate paper feed rollers 61, 62 of the intermediate paper feed part, and the leading edge of the recording paper sheet P is brought into contact with a registration shutter member 9A. Thus, the recording paper sheet is stopped and put in the stand-by state. Even in the standby state, the rotation of the registration roller 9 and the intermediate paper feed rollers 61, 62 is continued, and the leading half part and the trailing half part of the recording paper sheet P are a little subjected to the influence of the rotation so that the recording paper sheet is a little vibrated. The rotation system of the driven intermediate paper feed roller 62 supported by an elastic support member 63, however, does not cause a resonance phenomenon because inertia is applied by a weight 66 not to produce an abnormal noise.

Title: Thermal printer driving circuit
Inventor: MINOWA MASAHIRO
IPC: G06K15/10
Filed: 1980-12-29
Abstract: PURPOSE: To achieve a printing at a constant density following the indication of drop in the power source voltage by a drop in the density by comparing voltage levels of two voltage division circuits composing an energization range circuit which changes the energization time according to the power source voltage.  
     CONSTITUTION: Characteristic curves 71 and 72 indicate characteristics of first and second voltage division circuits respectively. As the potential n×Vd of the first voltage division circuit 42 is less than the voltage Vd-Vz, the power source voltage Vd initially follows the path from the point J to the point K and that from the point L to the point M when it is n×Vd>Vd-Vz. This is because the time at which the voltage regularly charged with a charging (53, 54)/discharging (56, 55) attains the same level as the reference voltage VC is determined by the larger value of Vd-Vz and n×Vd. This allows the power source such as manganese battery to be utilized in a wide range from the point J to M. In addition, at the point K, the print density changes suddenly providing a warning of limited residue of the battery.

Abstract: PURPOSE:To display a human image in a three-dimensional space as a real image by extracting the human image out of picked-up image signals, and displaying the human image and a background picture at such a time in different positions on a three-dimensional basis. CONSTITUTION:A human image extracting part 103 replaces the image signals in the background part with black signals, transmits only the human image to a stereoscopic image display part 105 on a receiving side as the image having ordinary luminance, and the display human image is displayed as a stereoscopic image 303 (real image) based on the principle of a stereoscopic video equipment. In addition, on the receiving side, the background picture assumed beforehand is separately prepared, displayed on a background image display television monitor 201, the background image is reflected by a half mirror 202, and it constitutes a background image 203. In such a case, a human image display television monitor 301 is displayed by a finite luminance value only for the human image, since the background is black, when they are overlapped, only the human image part is observed, and the picture background 203 of the background image monitor is observed as the background part. Thus the human image can be displayed as the real image in the three-dimensional space.
